burner suitable for starting and mamtainw ing a flame under conditions where no carbureter or separate atomizing apparatus is available, or at'least when it is not desired that the carburetor or atomizer shall be brought into use.

My invention comprehends a burner of rather simple cdnstruction having its various parts suitably arranged, whereby oil in. a liquid form and airunder pressure are.

admitted directly into the burner, the air in making its escape serving to atomlze the oil and thus form with it a combustible mixture. 1 Reference is to be had to the accompany- .lng drawings forming a part of this specifi-v cation, in which similar characters of refer.-

ence indicate corresponding parts in both).

Figure 1 is a substantially verticallongitudinal section through my improved burner; and Fig. 2 is a vertical cross-see tion on the line 22 of Fig. 1, looking in the direction of the arrow.

An outer barrel 3 is provided with a conical nozzle 4 havingl a hole 5 through it, this hole having generall the form of a cone frustum, the base of greatest diameter of the cone frustum extending outward, or, in other words, the hole in the nozzle being slightly flared. Disposed within the outer barrel 3 and concentric to the same is an inner barrel 6, having a conical nozzle 7 and a frusto-conical hole 8' through this nozzle, this hole being slightly of greater diameter at its outer end, that is to say, being slightly flared like the hole 5.

The inner barrel 6 is rovided with an annular rib 9 which comp etely encircles it and fits neatly within the outer barrel 3'so as to maintain the inner barrel concentric to the outer barrel. The inner barrel 6 is further provided with a hole 10 having generally the form of an inclined cone frustum and slightly undercutting a portion of the annu- -.bore of the inner barrel 6.

1 tion "21, terminating in Mounted 'l'ar bead 9. The inner barrel 6 is further rovided with a body portion 11, the latter eing comparatively thick and having a thread 12. This thread is engaged by a thread 13, wherewith the outer barrel 3 is provided adjacent to one of its ends. ring 14 encircles the body portion 11, and is fitted upon the adjacent end of the outer barrel 3, the ring and adjacent portion of this barrel being threaded for this purpose. Inside of the mug 14: and pressed against the adjacent end of the outer barrel 3 is a packing 15, whereby the portion 11 of the lnner barrel is rendered oil and gas-tight relatively to the outer barrel 3. Another ring 16, and a packing 17, are mounted upon the opposite end of. the body portion 11, and also serve to render the adjacent parts oil-tight and gas-tight.

The inner barrel 6, including its enlarged portion 11, is of a The enlarged portion 11 is threaded internally and is fitted with a screw plug 18 havlng an angular head 19, this head having a general angular form to enable it to be easily turned.

At 20 is a needle, and mounted upon the same is a piston 21, this piston sliding in a cylindrical compartment 6, that is, in the The needle 20 is provided with a forwardly-extended pora conical point 21, upon the needle 20 is a head 22, and engaging this head and encircling a small portion of the needle is a spiral spring 23, which presses against the angular head 19. 7

At 24 is a pipe which leads into the outer barrel 3 at a point between the annular bead 9 and the enlarged portion 11. At 25 is another pipe which taps into the outer barrel 3 at a point between the annular bead 9 and the conical nozzle 4.

The operation of my device is as follows: The operator, by turning the inner barrel, which he does by rotating its enlarged portion 11, varies the distance between the nozzles 4;- and 7. The supply of air passing out through the hole 5 is thus regulated within certain limits at will, and the shape and character of the air jet is changed to some extent. By adjusting the screw plug 18, which is done by turning the angular head 19, the position of the needle 20 relatively to the inner barrel is also adjusted at will. The screw plug 18 is of such length that, by

turning, it can be so adjusted that the piston 21 partially closes the hole 10, thus regulating the supply of oil. The operator by pressing upon the button 22, and thus compressing the spring 23, can cause the for- Ward end of the needle to pass out through the holes 8, 5, thus cleaning out these holes and insuring a free passage outward for the air and atomized oil. The operator, moreover, by pressing upon the button 22 and thus compressing the spring 23 so that the piston 21 is moved forward and partially obstructs the hole 10, can restrict the inflow of oil into the compartment 6 for a moment, that is, while the operator continues the pressure upon the head 22. Suppose, now, that everything is ready and that the operator desires to light a fire. He presses the button 22 forward, as above explained, thereby causing the needle point to be thrust through the holes 8, 5. The other parts being adjusted and the oil and air being turned on, the oil finds its way through the pipe 2 1 and hole 10 into the compartment 6, thence out through the hole 8 into the conical passage between the inner nozzle 7 and the outer nozzle 4. The air under pressure passilng through the pipe 25 and into the conical passage just mentioned, escapes out through the hole 5, and by aspiration breaks up the oil into a fine spray, so that there emerges from the hole an aeriform body made of mixed atomized oil and air. No carbureter is required for this burner, as the aeriform mixture issuing from the hole 5 is simply lighted with a match, or otherwise, and thereupon a flame issues from the hole 5.

I do not limit myself to the precise construction shown, the scope of my invention being commensurate with my claims.

- Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a burner, the combination of an outer barrel provided with a member having a hole through it, an inner barrel likewise provided through it, said holes being substantially in registrywith each other, a piston slidably mounted within said inner barrel, and a needle extending through said piston and provided with a portion in registry with said holes for enabling said needle to be thrust through said holes.

- 2. A burner comprising an outer barrel having a member provided with a hole, an innerbarrel concentric to said outer barrel and provided with a hole in substantial registry with said first-mentioned hole, a screw plug extending into said inner barrel and provided with a hole extending axially through it, a needle extending through said hole, a piston mounted on said needle and disposed within said inner barrel, and means for moving said needle and said piston forwardly for the purpose of thrusting said needle through the two holes first-mentioned.
